System Settings had grown to one long scroll (Integrations, Email, Audit,
Authentication, Asset Identifiers, Global Search, PC Type Mapping). Now a
vertical tab nav shows one section at a time, plus a search box that filters the
tabs by label/keywords (and shows every matching section while searching). Type
"toner" -> Integrations, "fqdn" -> Asset Identifiers, etc.
Frontend-only, behavior of each section unchanged. Build + naming green, verified.
